<p>Which is better for grammar, Grammatix or Rocket Review Revolution? I went to Amazon and read that the review for the Rocket Review revolution book and the book mostly got 5 star reviews. I got the book and noticed that it briefly reviews grammar. I think it only reviews the grammar that you need to know to get at least a 700 on the writing section. How is the grammatix book. I s it better than the Rocket Review Revolution Book?</p>
